QurLTlne- SPECIFICATION forming i'o cLZZ whom i7 may concern:

Be it known that 1, J osnrn THoMAs, of VHoboken, county of Hudson, State of `New' Jersey, have invented certain new and useful Improvements in SeWing-Machines'for Quilting, of which the following is a specification. This inventionrelates to that class of sew-` ing-machines such as is shown in the United States Letters PatentNo. 257,786, granted to `me May9, 1882, which is designed-toproduce lvarious quilting-patterns, and in which a row of needles moves laterally over the goods,and the feed-rollers are constructed to be adjusted `at different angles to the needles.

In the present invention two stationary rows `of needles are employed, and `the stitches made to produce the various patterns by giv-I ing to the feed-rollers and all other `parts that control the piece of goods to be quilted a lon, gitudinal movement-that is, a lateral move` ment to the goods at `the same time the feed` rollers are moved to feed the goods forward.' This I accomplish by means of `simple andeffective mechanism adapted to be adjusted and changed, so that the relation of the forward feed to the lateral movement of the goods is such as to produce stitches `of substantially equal lengths to produce the design desired.

Figure 1, Sheet 1, of the accompanying drawings, represents a front elevation of my improved sewing-machine for quilting, Fig. 2, Sheet 1, is a plan view of the same with the needle-carrying mechanism removed. Fig. 3, Sheet 2, is a transverse sectional view cut on the line y y, looking toward the left hand. Fig. 4, Sheet 2, is a similar view cut on the line .fr w; and Fig. 5, Sheet 2, is an end elevation, looking toward the right hand. Fig. 6, Sheet 3, is an enlarged detached elevation of the variable feed operating devices; and Fig. 7, Sheet 3, is a section of the same through the linez z, looking toward the right hand. a represents the main bed of the machine; b b, standards secured thereto, which carry the needle-bar c and shuttle-carriers d d. Two rows of needles, c and c2, are used, secured to one needle-bar c, which is operated through the medium of the connecting-rods c3 c3 and rocker-shaft c4 from the main driving-shaft e in the ordinary manner and by the usual connecting devices, as are the two sets of part of LettersyPatent No. 289,579, dated December 4, 1883. Appiicmon nlea February 10,1883.- (no man.) i

shuttle-carriers d d. Said connecting devices no partiof `my present invention.

It `will be observed that the needles have imparted to them only a vertical reciprocatf `ing movement to cause them to pierce the goods, which are given-a compound movement under the needles to produce the design def t sired bymeans of the devices as follows: The shaft f of the feedroller j" and the shaft of -the presser-roller g are fitted to slide longiings in the standards bb, to facilitate placing thegoods betweenlthem. These rollers f and i gareconnected together by means Yof plates f f/ g,so that the roller gis caused to move lon-` gitudinally with the rollerf. Fitted between fixed collars on the shaft fare two arms, h h, the front ends of which rest upon the curved Aguide-plateh, as ath2,Fig. 8. In these arms hh is fitted to rotatethe roller c', around which passes the endless apron i', carried at its other end by the small =roller ft2, also iitted to rotate in the arms h h. The roll of goods j to be quilti ed rests onthe endless apron on the roller t', I being held in slots formed inv the ends of the arms h h. The object of the endless ,apron is i to facilitate `the `forward movement `of the goods as they leave the roll j to pass under therneedles c c2 to the feedroller f By this arrangement of imparting directly to the feedroller a transverse movement, instead of moving the needles and their attending operating devices transversely over the goods, ormoving a heavy frame carrying the feed-roller, goods, Ste., a much less weight has to be moved. Consequently I am enabled to run this classv of sewing-machines at a greater rate of speed than heretofore, and the machines are made thereby more durable.

To impart the compound movement to the feed-roller f and its attending devices to control the goods, a gear-wheel, Z, is secured to its shaft f, which meshes into the long idlepinion l', driven by the gear-wheel Z2 on the shaft m, fitted to rotate in bearings rm m', secured'to the bed-plate a. On the inner end of the shaft m is secured the cam 11 actuating the lever 'n' bymeans of a rollerthereon. The lower end of this lever is pivoted to a bracket on the under side of the-bed at n2, and the uparelnot shown in the drawings, such forming tudinally, as well as to rotate in open bear- IOO ltents of such movements being governed by the configuration of the cam a and the amount of rotation given to the shaft m for each stitch made bythe needles. This variable intermittentxrota'tion of the shaft m is produced by means of a ratchet-Wheel, o, having teeth of different'lengths, and actuated by a pawl, 19, carried' by the lever p, pivoted on the shaft m and actuated by the'eccentricq on the drivingshaft e. e The throw of ,this eccentric is sufficient to move the pawl p over a distance equal to the longest tooth in the ratchet-wheel o.

To enable the pawl p to rop'erly catch in the various teeth in the ratc et-wheel o, a variable stop for the lever p is provided, which consists ofthe lever 1*, pivoted to the bracket 1",and having a projection, r2, adapted to bear onthecam s, and on the free end of the lever r is securedan adjustable arm, r, bent round at its lower end to holdup the lever p when y it is dropped by the eccentric q.

The rises of v the cam are so proportioned and bear such rclation to `the ratchet-wheel o that each time the ratchetis fed forward a tooth by the pawl p the stop r? retains the lever in the proper position for the pawl p to catch in the succeeding tooth of the ratchet, when the lever p is 'again raised bythe eccentric q.

Inl the .drawingsfFigsg 6 and 7 show the lever the lever r in position for thel action of the eccentric q. The pawl p is about to make its lshortest stroke.

InFigs. l to 5, inclusive, these devices 'are shown at the end of this tis a spring for holding the projection r2 of .v the lever 1' against the cam s.

The teeth in the ratchet-wheel o may be made vuniform in size, and the cam s made so as to cause the pawl p to move the wheel any d esired a and variable number of teethto impart -..the 5o right motion to the goods to produce the pattern desired. The vratchet o and Vcams n and s may be readily changed and replaced by. others to impart to the goods the right proportional amounts of longitudinal and transverse 55 movements for-anypattern of stitches'which lmay be produced by means of two rows "of to impart a uniformly compound movement to 65 the goods.

What I claim, and desire to secure by Letters Patent, isf' l. Ihecombination of the shaft f, carrying l y the feed-rollerf, constructed and operated by l7o means substantially.- as described, with the arms 7th, :rollers i and i2, apron d', and presser-roller g, asand for-the purpose set forth.
